HANDLE-ADJUSTING MEANS Application led February 23, 1928. Serial No. 256,311.

Our invention relates to brushes, mops and other articles involving a brush head or the like, and hereinafter referred to as the head, and more particularly to means for connecting a handlewith the brush head or the like.

The general object of our invention is toy provide a novel and effective means for so connecting the head with the handle as to permit the handle being readily swung laterally to one side or the other to vary its angle of position on the head.

A further and more specific object of our invention is to provide an assemblage in which the pressure of a spring is made effective, first, to hold the handle element and the mating base element in clutch or positive engagement, and secondly, to provide in association with a fastening means for securing the handle assemblage to the base kelement a frictional resistance opposing any tendency of the fastening means to loosen.

The nature of our invention and its distinguishing features and vadvantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specifica tion, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a perspective view of a brush head and handle embodying our invention with the connecting means thereon;

Figure 2 is a plan view;

Figure 3 is a longitudinal vertical section through the head and handle terminal;

rFigure 4 is a plan view ofthe fixed. clutch member or element attached to a brushhead or the like; 1 y

Figure 5 is an inverted plan view of the forward terminal of the handle showing the connecting clutch member.

In carrying out our invention in practice in accordance with the illustrated example, a base element 10 is provided adapted to be securedto the head A of a brush, .mop or similar article. Said base element 10 is formed Von the side with depending lips 11 adapted to give edge contact with the head A.

The base element 10 constitutes at its upper ber 15 mating the member 12 as shown clearly.4

in Figure 5.

For effecting an adjustable ment 10 we provide a fastener 16 in the general form of a bolt or screw which is provided with a 'head'v116 andwith ashank 17,y

said head and shank being receivable in a` pocket or recess 18 in the element 14, as clearly shownI in Figure. Shank isformed with areduc'ed lower end 19 to produce' va shoulder 20 at thefbase of said threaded zone 19. The reduced and threaded zonei1`9'of the fastener 17 is receivable in thel centraly bore or hole 13 ,of the basemember 10.

A. spring 21 is coiled,` about the shank 17, said spring abutting at its'upper end against the under side of the head 116 of the fastener 16. In the pocket or recess 18 in the handle element 14 there is an internal ledge or-shoulder 23 provided preferably with an annular inwardly directed flange of unbroken vcontinuity. Said ledge or shoulder 23 takes the pressure of the spring 21 at its lower end.

Since the pressure of the spring is upwardly against the under side of the head 116 ofthe fastener 16 and downwardly against l the flange 23 rigid vwith the handle element 14;.,the result is that the spring 21 tends to hold the mating clutch elements 12 and 15 in clutch and maintain the saine in firm engagement.

ilso, the pressure exerted on the under side of the head 116 of the fastener 16 resists any tendency Vof the fastener to become loose, theultimate purpose being to hold the handle in a given angular adjustment relatively to the lbase element 10. The element 10 may be secured in practice in any suitable manner to connectionl be,- Y tween the handle element 14 and the base elefrmw the head A, there being shown in said element holes 110 adapted tov receive fastening screws 24. Y l' The unscrewing of the fastener 17 to loosen its engagement with said element l0 permits of the handle B being turned to any desired angle laterally, the pressure of moving the handle laterally beingonlyV suficient to overcome the resistanceoffthe spring 2l to cause the clutch members to ride one over the other. To agaiirfirmly engage theclutclrelements the fastenerV 17 isscrewed irmlyto place.

le Wouldstate furthermore thatwhile vthe illustrated example constitutes a practical embodiment of our invention, We do not limit ourselves strictly to the exact details-herein illustrated, since, manifestly, the same can be considerably varied Withoutf departure from thespirit of the invention as defined in the appended. claim; A

We claim':

In a deviceV for adjustably securing a handle to ahead, including a base element having means whereby to secure the same to the head and'having a threaded hole therein, Vas Well as a' countersunk depression and a clutch surface'at the top outside of said depression and concentric With said hole, ahandle element' presenting at' its under side a mating clutch surface and having a pocket therein, an internal ledge on the handle element in said pocket, va headed fastener having a threaded 1- reducedzone adapted to engage the threaded hole inthe base element and having a shoulder at the base of said threaded-,zone adapted to bear againstthe bottomy of said counter.- sunk depression, anda spring in said pocket vand coiled` about said heade'dzfastener, said.

spring exerting. pressure at its upper end against the under side of the-head of the-fastener and'exerting pressure at its lower por tion against said ledge. f
